Pony Fantasy VI Remake

Problem. I added Grogar to the Tomb, the large room with Darill's coffin, but he doesn't want to behave, seemingly the Memory Byte part. I variably get him appearing in the middle of the water in one of the turtle rooms when I hit one of the water switches, or else leaving a room with such a switch causes the rom to crash. I know nothing of what the Memory Byte portion actually means so yeah, not quite sure what to do here. I will presume when I move the Smooze over I would encounter a similar problem as well.

Did you add custom event code? If so, this is likely the problem. What I understand is flipping a switch set the appearance bit of your NPC? Either you don't set the good bit or your custom code is making the game crash.

If the crash happen when you leave the room, it might be an issue with the entrance event of the map. More code / detail of changes could help as I don't remember well what is going on in vanilla Daryl's tomb..
